c++ find max code example

Example 1: max element in array c++ stl

*max_element (first_index, last_index);
ex:- for an array arr of size n
*max_element(arr, arr + n);

Example 2: how to use max_element in c++ with vector

int main() 
{ 
    // Get the vector 
    vector<int> a = { 1, 45, 54, 71, 76, 12 }; 
  
    // Print the vector 
    cout << "Vector: "; 
    for (int i = 0; i < a.size(); i++) 
        cout << a[i] << " "; 
    cout << endl; 
  
    // Find the max element 
    cout << "\nMax Element = "
         << *max_element(a.begin(), a.end()); 
    return 0; 
}

Example 3: max c++

// max example
#include <iostream>     // std::cout
#include <algorithm>    // std::max

int main () {
  std::cout << "max(1,2)==" << std::max(1,2) << '\n';
  std::cout << "max(2,1)==" << std::max(2,1) << '\n';
  std::cout << "max('a','z')==" << std::max('a','z') << '\n';
  std::cout << "max(3.14,2.73)==" << std::max(3.14,2.73) << '\n';
  return 0;
}
